Stripped hex screw on a SCAR 17

[DevsAdvocate 112]

Hey all, I was working on taking off my SCAR 17 and I stripped one of the hex screws holding the rails on... 

 

1.  Any tips on getting small stripped hex screws off?

2.  Where can I get replacement hex screw?  Most likely FNH, but I dunno how long it'll take to get from them..

1) carefully JB weld a wrench into the screw head and find a way to suspend it into place so it tries in square, when set unscrew as usual. Sure, you destroy the wrench but those are cheap. DO NOT SPILL JB weld outside the socket or you are really SOL.

Is there room to cut a slot in the screw, either with a Dremel or a hacksaw, and remove with a flat blade screwdriver?

Got it out with an EZ out and deep seep machine oil... sigh.  So much work!  Ordered new screws today.

You can't get the screw locally?

I found a source.  I need rail nuts as well since I crossed and mangled the threads getting them out too.

you can use a screw extractor, they sell them at all the major hardware stores..  You should use a light oil IE wd40 or so and let it sink in a bit

Did you hit the screw with a torch first to get the cement loose before you tried to unscrew it?  Those screws are a bitch to get out, everything I read tells you to heat em up real good first.  After leaving a torch on it for about 45 seconds Ive never had a problem backing them out (when they aren't stripped of course).
